Western Digital, which acquired SanDisk for $119 million in 2016, has announced the new SanDisk Extreme 400GB UHS-I microSD, the world’s fastest-ever UHS-I microSD card, with read speeds of up to 160MB/s and write speeds of up to 90MB/s. The read speed is over 50 percent faster than SanDisk’s current lineup of Extreme UHS-I microSD cards, notes PetaPixel. Western Digital says it’s also working on PCIe-enabled SD cards that will have even higher speeds for even more data-intensive camera features like 8K video and RAW continuous burst mode.DIY Photography has more.
